Editor to share with you how to use Collections.max () to maximize Java, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Rely on Collections.max () implementation

You can also find the maximum and minimum values using the Collections collection utility class, but before using it, we want to convert an array (Array) to a collection (List), as follows:

Import org.apache.commons.lang3.ArrayUtils

Import java.util.Arrays

Import java.util.Collections

Public class ArrayMax {

Public static void main (String [] args) {

Int [] arr = {3,7,2,1,-4}

Int max = findMaxByCollections (arr); / / find the maximum value based on Collections

System.out.println ("Max is:" + max)

}

/ * *

* find the maximum value based on Collections

* @ param arr Array to be queried

* @ return maximum

, /

Private static int findMaxByCollections (int [] arr) {

List list = Arrays.asList (

Org.apache.commons.lang3.ArrayUtils.toObject (arr))

Return Collections.max (list)

}

}

The results of the above procedures are as follows:

The maximum is: 7
